IMPROVEMENT IN THE MANUFACTURE OI YEAST FOR DISTILLERS.

The Schedule referred to in these Letters Patent and making part of the same I, J QSEPH WOLF'F,-of Lexington, in the county of Fayette, and State of Kentucky, have invented a new and useful Improvement in the Manufacture of Yeast for Distillers.

My improved yeast is produced by the following process: 7

'lake one hundred pounds of rye and fifty pounds of malt; heat Water to 175 or 180 Fahrenheit, and stir in, first the rye, and afterward the malt. Let it stay covered for one hour; then uncover, and let it remain for thirty-six hours, or until it acquires the wine-acid. Then cool the same down to 70 or 7 5 Fahrenheit, and, put to each one hundred fiounds, one and one-half gallons good fi'esh brewers yerst. Then take two ounces sal ammoniac and two ounces aloes; dissolve in warm water, (100 Fahrenheit,) andstir well into the above, and let it stay until it heats up 14; Should the yeast not reach therequired acidity, itmaybe stiinulated by exposure to the atmosphere, either by the rake. or paddle.

By the above process, yeast may a-lwavs be produced within forty-eight hours, if necessary, and. produce from fourteen to sixteen quarts of whiskey from each bushel of grain; thus complyingwith the'United States statute.

I claim, as my invention- The process for making distillers tially as herein shown and described.

In testimony of which invention, I hereunto set my hand.
